Wow, they sure are cramming a bunch of stuff into that figure now!

Whoever works on this, `sunpy.coordinates.get_horizons_coord()` will be your friend

> This appears to be an issue with `np.pad` ```python >>> import numpy as np >>> x = np.array([1.]) >>> np.pad(x, 1, constant_values=np.nan) array([nan, 1., nan]) >>> np.pad(x.astype('uint16'), 1, constant_values=np.nan)...

No, it should be a `ValueError`. We can't return a meaningful submap if one of the corners is NaNs.

@samiali12: On this repository, we typically don't assign issues to people. Feel free to go ahead and work on this, and submit a (draft) PR when you're ready.

This example has a number of issues: - This is not contouring, but rather masking. (We already have [an example that plots HMI contours on an AIA image](https://docs.sunpy.org/en/stable/generated/gallery/map/hmi_contours_wcsaxes.html).) - Using...

Heh, my question was rhetorical. The answer is no. None of our affine transformations are flux conserving.
